Specification of Letters Patent.

Patenti-noot. 29,1912.

Application filed May 17, 1912. Serial No. 698,007.

To all whom it may concern:

Be it known that I, RICHARD H. EVANS, a citizen of the `United States,blacksmith, and a resident of Riondel, in the Province of BritishColumbia, Dominion of Canada, have invented a new and Improved Oiler, ofwhich the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are:to provide an apparat-us of the character mentioned, wherein provisionis made for the exclusion of extraneous mattei', such as grit, dust,water, or similar substances; to provide means for insuring the supplyof oil when desired; to avoid leakage of oil from the apparatus; toinsure the steady delivery of oil during the employment of the oiler;and to provide means for locking the device in sealed position, toprevent. the delivery of oil therefrom.

Reference is to be had to the accompanying drawings forming a part ofthis speci- 'fication, in which similar characters of reference indicatecorresponding parts in all the views, and in which- Figure 1 is alongitudinal section, taken4 on the median line, of an oiler constructedand arranged in accordance with the present invention, showing the partsof the same in position assuined'while in' out-cfservice condition ofthe oiler; Fig.V 2 is a longitudinal section of. aY fragment of theoiler, sho-wing the parts arranged asin the service condition of theoiler and Fig. 3

is an end view of an oiler construct-ed andA arranged in accordance withthe present invention, the parts being shown in full lines inthetransition stage passing from one to the other, the out--of-service andin-service conditions above referred to, the dotted lines in this figurebeing used to show the normal disposition of the stopper locking bar.

As seen in the accompanying drawings,

beyond the orifice 10, the stopper 11 working under all conditionswithin the nozzle 9 or body 8 of the oiler. The stopper 11 may be coatedwith any suitable material adapting itself to use as packing but "Iprefer a stopper `having a wooden core, and under ordinary conditionslthe surface of the core is provided to so closely fit the nozzle 9 asto render the packing referred to unnecessary. There apacking or addedsurface for the stopper is employed, the body of the stopper isconstructed from wood, this material` lending itself most readily to themounting of the threaded plate 12, which mounting is accomplished byscrews 13,which are passed through said plate and driven into the bodyof the stopper 11.

The stopper 11 Vis manipulated by means of a rod-14. The rod 1-1 isfurnished with a screw-threaded end 15, the threads of which registerwith the threads of a perforation centrally disposed and provided in theplate 12. It is to lock the rod'14 in the plate 12 that I providek alock-nut 16, which, when jammed upon the plate 12, forms an effectivelock 'to prevent the recession of the rod lei. The end of the rod 14opposite the threaded end 15 is pivotally secured by a pin 17 betweenthe sides of a cut-out section of a locking bar 18. The ends of the bai11S are shaped as shown in the drawings, to extend within grooves 19,which are formed in the rounded rim 20 of the head .21. Access to thegrooves 19 is gained through recess 22, Whichfare formed by cutting awaythe rim 20, to pass-the ends of the bar 1S. When the .ends of the bar 18are held within the .grooves 19, as seen in Fig. 1 of drawings, thestop-per 11 is held firmly' in closure position within the nozzle 9. 18`is lifted out of the grooves 19 and turned- When the' bar from passingbetween the walls of the perfo-` ration formed in the nhead 21 and therod-14, a rubber packing 24- is employed. As shown inthe drawings, thispacking consists of a,

rubber ring mounted in a recess provided therefor in the head 21. Thepacking 24 is held firmly in position, and is expanded by pressureapplied upon the face thereof, by means of la Spanner nut 25.

The rod 14 may be constructed from tubiio ing, it being desired that ahollow passage shall be formed in the rod, between the orifices 26 and27. The said orifices forni the terminals of a passage formed in the rod14 for the admission of air to the chamber of the body 8. In Vthe o-uterservice condition, or when the stopper 1l is is position to close theorifice 10 of the nozzle 9, the orice 27 is housed within the body ofthe nut 25, to prevent the passage of air into the body 8. It will beunderstood that the perforation in the nut 25 lits the rod 14sufficiently close to prevent the passage'of oil from the said orificeout of the apparatus. If a tube be used to form the rod 14, a plug isdriven into said tube between the orifice 26 and the end 15,. If solidmaterial is used to form the rod 14, the end of the rod opposite the endl5 is bored longitudinally to forni the passage between the orifices 26and 27, and subsequently the end of said bore is closed by a plug. Anysuitable method of forming the orifices 26 and 27 and the connectingtubuv lar channel, is adapted to the needs of the present invention.

To limit the outward extension of the rod 14, and the lift of thestopper 11 from the orifice 10, I have provided a collar 28, rigidlymounted on said rod between the orifices 26 and 27.

I-Iaving thus described my inventionI claimas new and desire to secureby Letters Patent 1. In an o-iler such as described, the combination ofa tubular body portion having an end contracted to form a nozzleprovided with a delivery orifice; a stopper for said nozzle, shaped toconform to the interior of said nozzle; an operating rod for saidstopper, said rod extending through said body portion and beyond the endthereof; a closure head for the end of said body portion opposite thatforming the nozzle; means for admitting air through said head to saidbody, said means being operable'by said rod; a locking bar for said rod,to reciprocate the same; and an undercut rim formed on said body toengage said bar, tohold said stopper in position to close oi' open saidnozzle.

2. In an oiler such as described, the coinbination o-f a tubular bodyportion having an end contracted to form a nozzle provided with adelivery oriiice; a stopper for said nozzle, shaped to conform to theinterior of said nozzle; an operating rod for said stopper, said rodextending through said body portion and beyond the end thereof; a closure head for the end of said body portion opposite that forming thenozzle; means for admitting air through said head to said body, saidmeans being operable by said rod; a locking bar for said rod; anundercut rim formed on said body to engage said bai' to hold saidstopper in position to close or open said nozzle; and a stop collarmounted on said rod to limit the movement thereof.

3. In an oiler such as described, the coinbination of a tubular bodyportion having a nozzle-shaped end provided with a dclivery orifice; astopper shaped to conform with the inner shape of said nozzle; a closurecap for t-lie end of said body portion opposite said nozzle; aconnecting rod rigidly secured to said stopper extended through guideperforations in said cap, said rod being provided with a channel havingan opening within said body portion and an opening adapted for extensionbeyond said cap; an expansion packing disposed in said cap to surroundsaid rod, to close the passage between said cap and said rod; and adouble-extension undercut rim for said cap adapted to receive thereundersaid handle when said stopper is in closed position in said nozzle, oneend of said channel formed in said rod being, in this position, withinand closed by said cap.

In testimony whereof I have signed my naine to this specification in thepresence of two subscribing witnesses.
